BTU Calculation Formula:
From: | To: |
Definition: This calculator converts the power output of radiators from kilowatts (kW) to British Thermal Units per hour (BTU/h).
Purpose: It helps UK homeowners and heating engineers compare radiator outputs and select appropriate heating solutions.
The calculator uses the formula:
Where:
Explanation: 1 kW is equivalent to 3412 BTU/h, as this is the standard conversion factor between these units.
Details: Proper BTU calculation ensures your radiators provide adequate heat output for your room size, improving energy efficiency and comfort.
Tips: Enter the radiator's kW rating (found on product specifications) to get the equivalent BTU output. The value must be > 0.
Q1: Why is BTU important for radiators?
A: BTU measures heat output, helping you match radiator capacity to room heating requirements.
Q2: What's a typical BTU requirement for UK rooms?
A: Approximately 5,000 BTU for small rooms (10m²) up to 15,000 BTU for large rooms (25m²).
Q3: Should I round up the BTU result?
A: Yes, it's common practice to round up to the nearest 500-1000 BTU when selecting radiators.
Q4: Does this account for room insulation?
A: No, this is a basic conversion. Actual heating needs vary based on insulation, windows, and other factors.
Q5: How do I find my radiator's kW rating?
A: Check the product specifications or manufacturer's documentation.
